Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Primary Electrical Criteria:

• Resistance value: 2.21 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Criteria:

• Package type: 0805 (2012 Metric)
• Composition: Thick Film
• Termination count: 2
• Physical dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm)

Compliance Criteria:

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected or REACH Compliant status

Parts are grouped into two categories:

Direct Substitutes: Identical electrical specifications, mechanical package, and compliance status. These parts are interchangeable without design modification.

Similar Substitutes: Meet all core electrical and mechanical requirements but include additional features (automotive AEC-Q200 qualification, pulse withstanding capability) or differ in packaging format (Cut Tape vs. Tape & Reel). These parts are functionally compatible but may require application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical Specifications):

CR0805-FX-2211ELF (Bourns Inc.), RC0805FR-072K21L (YAGEO), and RMCF0805FT2K21 (Stackpole Electronics Inc) are direct electrical and mechanical equivalents to RC2012F2211CS. All three maintain 0.125W power rating, ±1% tolerance, ROHS3 compliance, and identical operating temperature range. These parts are suitable for one-to-one replacement in standard applications.

For Automotive Applications:

ERJ-6ENF2211V (Panasonic), RMCF0805FG2K21 (Stackpole), RMCF0805FT2K21 (Stackpole), AC0805FR-072K21L (YAGEO), CRCW08052K21FKEA (Vishay Dale), and CRCW08052K21FKTA (Vishay Dale) include AEC-Q200 automotive qualification. These parts are suitable for automotive-grade applications requiring enhanced reliability standards.

For Packaging Format Consideration:

RMCF0805FG2K21 is supplied in Cut Tape format, differing from the standard Tape & Reel packaging of RC2012F2211CS. This variant is suitable for applications where Cut Tape handling is compatible with assembly processes.

For Higher Power Dissipation:

CRCW08052K21FKEAHP (Vishay Dale) and RCS08052K21FKEA (Vishay Dale) provide 0.5W (1/2W) power rating with pulse withstanding capability, exceeding the 0.125W specification of the original part. These variants are suitable only when higher power dissipation is required and circuit design permits the substitution.

Compliance Consideration:

CRCW08052K21FKTA is RoHS non-compliant and REACH Affected. This part is not suitable for applications requiring ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-2211ELF replace RC2012F2211CS directly in production?

A: Yes. CR0805-FX-2211ELF meets all electrical specifications (2.21 kOhms ±1%, 0.125W), mechanical dimensions (0805 package), and compliance requirements (ROHS3 Compliant, MSL 1). No design modification is required.

Q: What is the difference between RMCF0805FG2K21 and RMCF0805FT2K21?

A: Both parts are electrically and mechanically identical with AEC-Q200 automotive qualification. The primary difference is packaging format: RMCF0805FG2K21 is supplied in Cut Tape (CT), while RMCF0805FT2K21 is supplied in Tape & Reel (TR). Select based on assembly equipment compatibility.

Q: Can CRCW08052K21FKEAHP be used as a substitute for RC2012F2211CS?

A: CRCW08052K21FKEAHP is electrically compatible in resistance and tolerance but differs in power rating (0.5W vs. 0.125W). This part is suitable only if the circuit design permits higher power dissipation. The 0805 package dimensions remain identical.

Q: Why is CRCW08052K21FKTA listed as a similar substitute if it is RoHS non-compliant?

A: CRCW08052K21FKTA meets all electrical and mechanical specifications but fails compliance requirements. It is included for reference in applications where RoHS compliance is not mandated. For new designs and regulated applications, ROHS3-compliant alternatives are required.

Q: Are all substitute parts rated for -55°C to 155°C operating temperature?

A: Yes. All listed substitute parts maintain the identical operating temperature range of -55°C to 155°C, matching the original RC2012F2211CS specification.

Q: What does AEC-Q200 qualification indicate?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts bearing this rating have undergone enhanced reliability testing and are suitable for automotive applications. This qualification is optional for general-purpose applications but required for automotive-grade designs.

Q: Can I substitute a 0.5W resistor for a 0.125W resistor in the same circuit?

A: Substituting higher power-rated components is physically possible due to identical 0805 package dimensions, but circuit design must accommodate the change. Higher power ratings do not automatically improve performance in circuits designed for 0.125W dissipation. Evaluate thermal and electrical characteristics before substitution.

Q: Is Moisture Sensitivity Level 1 (Unlimited) the same across all listed parts?

A: Yes. All listed parts, including the original RC2012F2211CS, are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
